FRANCIS J. LA FORME, OF BOSTON, MASSACHUSETTS.

NURSING-BOTTLE.

Specication forming` part of Letters Patent No. 26,327, dated November 29, 1859;Beissued s January 14, 1868, No. 2,831, i, p p t y y Be it known that I, FRANCIS J. LA FonME, of Boston, in the county of Suffolk and State of Massachusetts, have invented an `Improvement in Nurse-Bottles; and I do tion thereof.

The nature'of my invention consists in applying, within or to the mouth or neck oft a nurse bottle, a flexible tube whereby the nutriment contained in such bottle can not onl `be drawn outof the same, with equal faellity in Whatever position the bottle may be placed, butV the child or infant be prevented from inhaling air therefrom, the said tube being composed of india rubber or its equivalent, and having an enlargement or tip applied to one or both of `its ends, in manner as will be hereinafter specified.

. It is a fact Well known to physicians and nurses or those having the care of infants (forced by necessity or otherwise to derive their` nourishment from other than their natural sources) that a good, cleanly and` silbstantia-l nurse bottle has been a desidera.-

` objectionable, owin tuin that has lou,r existed. 'lo supply this need, various devices or bottles have been 1nvented. Some of these have been con `structcd entirely of metal which owing to its oxidation, renders it totally unfit for placed in themand suffered to remain for f a short time causes oxidation to take place on the' inside of the bottle such not being seen is often suffered to remain to the great injury of the child using` such bottle. Others have been made with a glass body and a metallic cap, and tube extending down into` the interior of the bottle. These are also to the difficulty of keeping such metallic parts from oxidation., t

\ Others still have been made entirely of f v glass, with the exception of the rubber nipp y enlargement or tip d upon one or both of its t thereto in manner and ple. The evil incident tofthetlatterl bottlefo` is the great diliculty of cleansing the bent` eduction tube Without breakagethereof, and

moreover another serious t disadvantage, which all of the above possess,`ariseslfro1n the inflexible bent form of their; eduction thatthe mouths of suchztubesshl always i be placed downward to prevent the child or infant from inhaling air `andto` enable it if to obtain the liquid contentsfof the;bottlefif` fifi thereto when drawn over bottle as seen in Fig. l.`

In order to 4renderit impossible for the child to inhale air `from the bottleinstead of nutriment` Idispose withinthe bottle a` flexible tube C, (made of india rubber or its equivalent) the saine being,` `formed with an ends. The tipor tips I usually constructief` l:

glass and of the fol-1n asshown in the drawlng, one of the tips resting against theneck or month of the bottle. Thus it will* be "ob- I vious that with a' bottle provided with `my brings the lower tipor endof the `into the milk whatever may be? the posxtlon` ofl the bottle, thereby rendering `any rare astdl essai-y. t y t i y Having described my invention,vv what `l claim is An improved nurse bottle, or one havingk an elastic tube, constructed `andyapplied@` y forthe' purpose set? l forth.
